Will my MacBook Air and Iphone chargers work in Prague if I buy a Type E/F power adapter?

I will be living in Prague this summer, and I need to buy adapters/converters for my American products. I have done some research, but I'm still a bit confused on voltage/watts type of stuff.

I read that Czech Republic uses 230V. I checked on both of my Macbook and Iphone charger, and they said 100-240V. So I don't need to buy a converter as well for my laptop and phone, right? It also says 50-60 hz. Not sure what that means?

I just want to make sure I don't have to buy a converter for my products as well. Also want to make sure that the type e/f adapter will work

My car was broken into and one month new Iphone 6 64GB was stolen?

Please help me, I accidentally left my phone in my car. Next morning I remembered went to the car to find the window smashed and my phone taken. I had the Find my Iphone on it, but it keeps saying offline. I have been refreshing and checking on the app consistently and it always says offline. Already file a police report and they told me they "don't help with stolen phones and breaking a car window is not even worth reporting". I didn't have insurance. Is there anything that can be done>>? Should the cops be more helpful, it is so hard for me to believe that a cops job is to find criminals and prevent crimes and yet they can't do anything.
